"Companies today are going through a big transition: Business models are changing. A vendor's success depends on a customer's success, and we need to start using the best practices and big data technology that is applied to customer acquisition to the area of customer retention," said Nick Mehta, CEO of Gainsight, which just this week completed a $9 million Series-A funding round. "Companies have a huge digital breadcrumb trail of customer data, but it's siloed across systems and departments and not well-leveraged. Gainsight is solving this problem by analyzing customer vital signs to reduce churn, increase up-sell, and maximize customer success."
